运用古地震数据分析布朗过程时间模型中强震复发间隔变异系数
Aperiodicity parameters of reoccurrence intervals of large earthquakes in the Brownian passage time model based on paleo-earthquake data
摘要
Abstract
Based on the 45 seismic sequences collected in Chinese mainland,the maximum likelihood estimation method is used to calculate the variation coefficient of earthquake sequences with different sample size,and the correlativities with the parameters of the corresponding fault source are carried out,and then the estimated values are standardized.Finally,a general value ac=0.37 of aperiodicity is given.The results of the correlation analysis show that the variation coefficient is negatively correlated with the length of the fault and the horizontal slip rate,so the application of the general aperiodicity value (αc=0.37) is analyzed.The result show that the three a values (0.2l,0.37,0.53) obtained by performing standard deviation operation to αc are applied to the active faults with significantly differences in characteristics.关键词
